METAL STORM WINDOW AND SASH THEREFOR Filed April 5, 1957 s Sheets-Sheet 3 INVENTOR. HAROLU A. ETL/IVG ATTORNEY$ 3 038,570 METAL STURM WINfiOW AND SASH THEREFOR Harold A. Etling, Marshallville, Qhio, assignor to ilgather-Seal, Inc, Barberton, Ohio, a corporation of Filed Apr. 5, 1957, Set. No. 651,013 7 Claims. (81. 189-76) This invention relates to storm or auxiliary windows and to sashes therefor, especially to storm windows, sashes and frames particularly adapted to be made from metal and to mount the sashes for easy sliding action.

'Heretofore many efforts have been made to provide storm window constructions that will meet with complete public approval and acceptance. These storm windows in many instances have been made from wood, whereas other styles of construction have utilized extruded metal shapes in forming storm Window frames, sashes and the like. At the present time, many so-called self-storing storm windows utilize some type of a triple track construction wherein two window sashes are received in two of the tracks, and the third track receives the screen which is permanently positioned in the window frame. The screen is moved up or down in correlation with movement of one window sash for operative or inoperative positioning of the screen, as desired. Various other types of self-storing windows likewise maintain a window, or a screen, in the window opening even when such window or screen presumably is inoperatively positioned. It is diflicult to slide or move the different sashes in many of these storm windows.

The general object of the present invention is to prowide a novel metal storm window characterized by the ease of sliding metal window sashes in a metal frame.

Another object of the invention is to provide a metal storm window with plastic runners therefor so that a metal to metal contact is avoided between relatively slidable portions of the window construction.

Further objects of the invention are to provide a new type of a storm window which is of compact, sturdy construction and which can be relatively easily assembled by substantially unskilled labor; to provide novel extruded metal shapes having desirable properties for a metal window sash; to provide novel means for securing components of a metal window sash together; and to provide novel sash frame means and plastic runners therefor.

The foregoing and other objects and advantages of the invention will be made more apparent as the specification proceeds.

When referring to the accompanying drawings and the following specification, corresponding numerals are used to refer to corresponding parts to facilitate comparison between the drawings and specification.

It should be understood that one currently preferred embodiment of the invention is shown in the drawings and is described hereinafter in detail, and that the drawings comprise the following:

FIG. 1 is an inside front elevation of the storm window of the invention;

FIGS. 2 through 6, inclusive, are detailed enlarged sections taken on line 22, 3-3, 4-4, 55 and 66, respectively of FIG. 1;

FIG. 7 is an enlarged fragmentary section through a corner of a window sash of the invention showing how the components thereof are secured together;

FIG. 8 is a fragmentary enlarged elevation showing a lower corner of the upper sash and the latch positioning means therefor; and

FIG. 9 is a section through a sash rail and a plastic sash runner strip.

, The metal storm window of the invention includes two "United States Patent C) that terminate on main Patented June 12, 1962 double hung metal sashes of special construction, a roll screen assembly, supplemental rails extending the window height and having laterally outer closed channel portions with each such channel having a lug extending axially inwardly of the window, which supplementary rails have axially outwardly positioned sash engaging flanges and axially inwardly opening positioning recesses, upper and lower sash parting strips engaged with different vertical portions of the supplementary rails and having flanges for engaging the positioning recesses in order to engage such parting strips with the supplementary rails. The lugs on the supplementary rails also engage parts of the sash parting, strips to aid in positioning such strips and retain them in engagement with the as sociated portions of the supplementary rail.

In describing the storm, or auxiliary window of the invention, the word axially is used to describe the line normal to a plane defined by the storm window of the invention and with the inner surface of the storm window of course being the surface facing within the build- Attention should now be directed to the details of the construction shown in the drawings, and the storm window of the invention is indicated as a whole by the numeral 1. The storm window assembly is positioned within a conventional window frame 2. that forms part of a residence, oflice building, or the like. The storm window 1 includes a pair of double hung sashes comprising an upper sash 3 and a lower sash 4 with a housing 5 being provided at the lower portion of the storm window 1 for storing a roll screen therein.

Storm Window Frame and Runner Means The storm window of the invention comprises as an outer adjustable connecting window frame for engaging the building frame 2, a plurality of metal channels 6 which extend vertically of the storm window 1 the entire height of the frame 2, and a similar top metal channel 7 that is of the same sectional shape as the side channels 6. These channels 6 and 7 all have an axially outwardly directed lip or flange 8 thereon and suitable holes (not shown) are drilled in the channels 6 and '7 in the corner provided between the flanges 8 and the remainder of the channels so that screws-or nails can conveniently be engaged with such holes for securing the channels to the frame 2. The channels 6 and 7 are all positioned with the closed base portions thereof extending laterally outwardly of the frame for the storm window 1, and axially inwardly extending lips 9 are provided on the laterally inner edges of the axially outer legs of the channels for a purpose to be hereinafter described.

To position the sashes 3 and 4 in the window, supplementary rails 10 engage the side channels 6 and extend the height of the storm window 1 whereas a similar supplementary rail 11 is engaged with the top channel 7 for providing sash engaging means for that portion of the window.

The supplementary rails 10 and 11 are provided with a substantially U-shaped laterally outwardly positioned base portion, the axially inner legs ltia and 11a of which are short in length and have lugs 12 directed axially inwardly of the storm window 1 formed integrally therewith. The axially outer legs ltlb and 11b of the sup plementary rails extend laterally inwardly of the storm window 1 and protrude appreciably from the associated channel members 6 and 7, all as best shown clearly in FIGS. 2 through 4. The laterally inner portions of the supplementary rails include sash receiving portions 13 their axially outer surfaces in sash engaging flanges 14 immediately adjacent the sash receiving portions 13 of the supplementary rails on a laterally outer portion thereof. The sash receiving portions 13 are provided with suitably contoured, angularly positioned receiving recesses 15 directed laterally outwardly, but axially inwardly of the storm window on an axially inner surface thereof.

The upper sash engaging portion of the storm window frame means is completed by means of roughly Z-shaped upper sash parting strips 16 positioned both in upper lateral margins of the supplementary rails and in the top supplementary rail 11. The upper sash parting strips have sash engaging flanges 17 on their laterally inner margins, whereas an angularly positioned axially outwardly directed lug 18 is also provided on each of the upper sash parting strips and these lugs engage the recesses to aid in positioning the upper sash parting strips 16. FIG. 2, for example, shows the lug 18 on the upper sash parting strip 16 and how it is contoured to mate snugly with the complementary recess provided in the supplementary rail 10. The other upper sash parting strips 16 are similarly engaged with the supplementary rails associated therewith. The flanges 17 of the upper sash parting strips, and the flanges 14 of the supplementary rails 10 cooperate to form a channel in which the upper sash 3 is positioned. The laterally outer ends of the upper sash parting strips 16 have axially outwardly directed fingers or flanges 19 provided thereon which bear against the axially inner legs 10a and 11a of the channel shaped bases of the supplementary rails 10 and 11 and, when the storm window is assembled, aid in maintaining the upper sash parting strips 16 snugly positioned between the side and upper channels 6 and 7 and the supplementary rails associated therewith. The lugs 12 on the supplementary rails 10 and 11 are peened or crimped over at several spaced portions thereof against the adjacent flanges of the upper sash parting strips 16 to retain the parting strips in engagement with the supplementary rails prior to the engagement of the supplementary rails with the channels 6 and 7, and a tight assembly of the channels and rails is provided.

A bottom sash parting strip 20, shown in FIG. 3, is provided on each lateral margin of the storm window, and it is generally U-shaped in section. The lower sash parting strips have lugs or flanges 21, like the lugs 18 on the upper sash parting strips 16, extending angularly laterally inwardly and axially outwardly of the storm window and such lugs 18 are snugly received in the lower portions of the recesses 15 provided in the supplementary rails 10. Likewise, an axially inner, laterally outer portion of each of the lower sash parting strips 20 has a flange 22 thereon which engages the leg 10a of the supplementary rails 10. The lugs 12 likewise are folded, staked or peened over at several places against the surface of the flanges 22 to retain the supplementary rails 10 and the lower sash parting strips 20 in engagement so that the unit so provided can he slid into engagement with the channels 6.

The axially and laterally inner portions of the bottom sash parting strips 20 have shoulders 23 provided therein to aid in defining a bottom or lower sash receiving laterally inner end in such parting strip. These shoulders 23 also aid in providing a narrowed screen receiving open portion in the lower sash parting strips 20 to prevent the entry of bugs or foreign matter around the lateral portions of the roll screen.

Window Sash Construction The upper and lower sashes 3 and 4, respectively, both are made from metal sash members 24, FIGS. 2 and 7, which are substantially H-shape in section. The laterally inner portions of the sash members 24 engage with and position a window pane 25 by suitable plastic tapes or glazing channels 26.

In order to prevent the window sashes from having metal edges for abutting on the metal runners provided in the supplementary rail and sash parting strips of the storm window, it is an important feature of the invention that plastic runner strips 27 be provided for forming the actual slide contact between the window sash and the associated positioning means. These runner strips 27 may be made, for example, from any suitable hard, low friction plastic material, such as polyethylene or nylon. The runner strips are of substantially T-shape in section and with the exposed ends of such plastic strips being wider than the associated sash members 24. It will be noted that the laterally outer portions of the sash members 24 have a plurality of shoulder stop means or notches 124 provided therein and directed laterally inwardly thereof. Complementary shoulders indicated at 127 are provided on the runner strips 27 and the shoulders are connected by notched portions, or ramps and face outwardly of the sash assembly. Such runner strips 27 can be pressed into engagement with the outer edges of the sash members and be locked snugly together therewith by the shoulders 3127, as the sash runners taper outwardly in width up to the shoulders 127 to facilitate pushing or rolling the shank portions 27a of the runner strips into engagement with the edges of the sash members 24.

FIG. 7 shows how the corners of a sash frame are assembled and a corner key 28 is provided that is slidably engaged with the laterally outer portion of a sash member 24a intermediate the web thereof and the associated shoulder 124. This corner key 28 is provided with a pair of recesses 29 in the inner surface thereof so that a web 30 of the sash member 24a can be punched or staked out of its normal position into the recesses 29 to retain the corner key 28 locked to such sash member 24a, as indicated in the drawings. The other sash member 24b is positioned normal to and abutted against the end of the sash frame member 24a and a hole 31 is drilled in the web of such sash frame member. A screw 32 extends through the web of the sash frame member 24a and engages a tapped hole in the corner key 28 to lock the sash frame members in assembled relation.

FIG. 6 of the drawings shows how the upper sash 3 may have a sash member 24x at the lower margin thereof, and the lower sash 4 has a sash member 24y at the upper margin thereof so that complementary shaped engaging surfaces can be provided on the adjacent meeting rails of such sashes, even though the sashes are axially offset, as shown in the drawings, to provide a snug, air-tight fit between such window sashes when they are closed.

Screen Positioning Means As indicated in FIG. 5, the same means are used to position the roll screen housing 5 in the storm window 1, as are used to complete the outer framework of the storm window 1 for filling the frame 2.

FIG. 5 shows that the housing 5 suitably positions a roll type screen 33 therein which screen is shown received upon a roll 34 of a conventional construction journalled in the housing 5 by conventional means. The upper end of the screen 33 may have an edge member 133 associated therewith by being folded over the screen edge and such member 133 and screen are doubled back upon themselves to be snugly received in a recess in a screen rail '35. This screen rail 35 has an upwardly extending flange 36 loosely received in the downwardly open edge of a lower sash member 24m of the lower sash 4. The screen rail 35 also has an axially inwardly and downwardly directed flange 37 on an inner portion thereof which aids in sealing the lower sash 4 to the frame portion of the storm window 1 when the screen 33 is in its stored position. A bottom supplementary rail 38 is provided and it extends between the supplementary rails 10 at the lower ends thereof. Such bottom supplementary rail 38 has an upwardly extending flange 39 thereon engaging the lower surface of the flange 67 on the screen rail and, if desired, suitable sealing means or tape can be carried by the flange 37 on its lower surface to aid in forming a seal between the flange 37 and the flange 39.

The bottom supplementary rail 38 also has a special contoured recess 40 on an axially inwardly extending edge flange 41 thereof. A bottom finishing rail 42 is provided and is positioned on the inner surface of the storm window 1 by an edge portion thereon engaging the special contoured recess 40 on the flange 41 of the supplemental bottom rail. The bottom finish rail 42 has mitered upper corners that abut against mitered lower ends of the supplementary rails 10.

The height of the bottom portion of the storm window 1 is made adjustable by means of an adaptor plate or strip 43 received between the bottom supplementary rail 38 and the bottom finish rail 42. Suitable screw means may extend between these three members, after the adaptor plate 43 has been pulled from its associated positioning means a sufficient distance to rest against the top of the sill portion of the frame 2.

The screen rail 35 normally has two handles 44 secured thereto by screws to facilitate raising the lower sash 4 and the screen 33 as a unit by unrolling the screen 33 and simultaneously pulling it up as the lower sash is raised.

The lower sash 4 is engaged with the screen rail 35 by means of spring clips 46 secured to the lower portion of the frame of the lower sash 4 and protruding downwardly therefrom for individual engagement with locking lips on a base portion of the handles 44. By-sliding the lower sash 4 downwardly, the clips 46 will automatically ride up over the handles 44 until the lower portion of the clips 46 engage the lips after which unitary movement of the lower sash and roll screen will occur as the lower sash is moved.

It will be appreciated that the lower sash 4 may be retained in any of a number of desired vertical positions for operatively positioning portions of the screen 33. In the construction shown, the roll screen 33 may be completely stored upon the roll 34 or the lower screen may be lifted several inches to provide a ventilation opening.

The top sash positioning means, as indicated in FIG. 8, include latches 53 slidably carried in the lower portion of the sash frame member 24x of the upper sash. The latches 53 are urged laterally outwardly of the window sash 3 by coil springs 54 received in slots 55 in the latches. The latches 53 are engaged with the window sashes by pins 56 extending through the slots 55 and engaging the sash frame. The latches 54 may have little knobs or handles 57 provided on their laterally inner ends to facilitate pulling the latches in for free sliding movement of the upper sash 3.

Spring clips 64 are secured to the upper sash parting strip 16 that engages the top supplementary rail 11 and extend downwardly therefrom to engage the lower sash 4 when it is raised.

While the invention particularly relates to storm windows made from metal, such as aluminum, the novel construction of the invention may be made from other suitable materials when desired.

Nails or screws 67 extend through holes provided in the flanges 8 on the channels 6 and 7 to permit such securing means to extend directly into the frame 2 and facilitate positioning the channels in position.

In general it should be realized that the frame positioning means for the upper and lower sashes 3 and 4 may be of any desired construction. The novel plastic runner strips 27 of the invention are readily and easily engaged with the frame sash members 24, or equivalents to be carried thereby. The sash members 24 are easily and positively secured together by means readily engaged therewith and ultimately hidden from view. The key 28 used to secure the sash members 24 together is hidden by the sash runners.

Thus an attractive, sturdy window sash has been provided by the invention. The metal window sash will slide readily over associated metal surfaces and will not gall or freeze thereto. Hence, it is believed that the objects of the invention have been achieved.

This is a continuation-in-part of application Serial No. 363,449, now Patent No. 2,826,789 issued March 18, 1958.
